I have used limewire (pro) for more than 2 years now on my imac G4 superdrive and wanted to install the programme on my wife's imac g3. Tried to download limewire basic 4.08; download starts, but the limewiremac.bin on the desktop is 'empty', when i double-click it, it tells me that it cannot install, the programme it needs is not available. Am i missing something?
